Hybrid tea rose plant named Devcico

ABSTRACT

A new hybrid tea rose plant producing pink flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class which was originated by crossing as seed parent the variety known as `Dolores` and as pollen parent the variety known as `Cerise Dawn`. The varietal denomination of this new rose is `Devcico`.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive pink flowers having a classic balled center.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

Parentage: Seedling.

Seed parent.--`Dolores`.

Pollen parent.--`Cerise Dawn`.

Class: Hybrid tea.

The following is a detailed description of my new variety, of new specimens grown under glass in Watsonville, Calif. in the month of September. The color terminology used is in accordance with the Royal Horticultural Society Colour Chart (RHSCC), and refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending on light, environmental and cultural conditions.
